Indian Central Law

What is this right?

Small businesses and professionals in India can compute income under simplified presumptive taxation schemes, avoiding the need for detailed accounts.

Section 44AD (Small businesses): Businesses (not professionals or certain specified businesses) with annual turnover up to ₹3 crore (₹2 crore for those not accepting digital payments) can declare income at a flat 8% of gross receipts (6% if receipts are through banking channels). This is the presumed income — no need to maintain detailed accounts or get an audit.
Section 44ADA (Professionals): Professionals (doctors, lawyers, chartered accountants, engineers, architects, etc.) with gross receipts up to ₹75 lakh can declare income at a flat 50% of gross receipts — no detailed accounts or audit required.
Section 44AE (Goods carriage operators): Flat income of ₹7,500 per month per vehicle for goods carriage operators owning up to 10 vehicles.
Opting out of 44AD and declaring lower income requires maintaining books and getting an audit (s. 44AB) for the next 5 years.
Advance tax is payable in a single instalment by 15 March if using the presumptive scheme.

When does it apply?

You are a small trader, shopkeeper, or contractor with turnover below ₹3 crore.
You are a doctor, lawyer, or engineer earning professional fees below ₹75 lakh per year.
You want to avoid the cost and complexity of maintaining detailed books of accounts.

What to Do If You Are a Small Business or Professional Who Qualifies for Presumptive Taxation in India

Select ITR-4 (Sugam) when filing your return — this form is specifically designed for taxpayers under s. 44AD, 44ADA, and 44AE.
Pay the entire advance tax (based on presumed income) in a single instalment by 15 March to avoid interest under s. 234B/234C.
Maintain basic bank statements and invoices even under the presumptive scheme — the department can ask for these in a scrutiny assessment.

What should you NOT do?

Do not opt out of the presumptive scheme in any one of the 5 years without being prepared to maintain full accounts for the entire 5-year block — one opt-out locks you into full accounts for 5 years.
Do not use the presumptive scheme if your actual profit margin is significantly higher than the prescribed rate — you still pay tax on the presumed income even if actual profit is lower, but declaring higher actual income may be beneficial.
Do not exceed the turnover limits (₹3 crore for 44AD, ₹75 lakh for 44ADA) without switching to the regular scheme with mandatory audit — exceeding limits without audit attracts penalties under s. 271B.

Tamil Nadu Law

How Tamil Nadu differs from central law

Presumptive taxation under the Income Tax Act provides simplified tax computation for small businesses and professionals — widely used in Tamil Nadu's large small-business and self-employed sector.

Section 44AD (for businesses): Resident individuals, HUFs, and partnership firms with turnover up to Rs 3 crore (if digital receipts are at least 95% of total receipts; Rs 2 crore otherwise) can declare income at 8% of gross turnover (6% for digital receipts) without maintaining detailed books of accounts.
Section 44ADA (for professionals): Resident professionals (doctors, lawyers, chartered accountants, engineers, architects, etc.) with gross receipts up to Rs 75 lakh (if digital receipts are at least 95%; Rs 50 lakh otherwise) can declare income at 50% of gross receipts.
Tamil Nadu has a very large population of small traders, shop owners, and self-employed professionals who benefit from presumptive taxation. The scheme is particularly popular among textile traders in Tiruppur, small manufacturers in Coimbatore, and service providers across the state.
Under the presumptive scheme, you are not required to maintain books of accounts or get them audited (unless you declare income below the prescribed percentage).
Advance tax under the presumptive scheme must be paid in one instalment by 15 March of the financial year (rather than the usual quarterly instalments).

Additional Steps in Tamil Nadu

File your income tax return using ITR-4 (Sugam) if opting for presumptive taxation. Declare income at or above the prescribed percentage (8%/6% for business, 50% for professionals). Pay advance tax by 15 March. If you fall below the turnover threshold, you may switch to regular computation — consult a chartered accountant. For disputes, appeal to the CIT(A) and then the ITAT Chennai Bench.
